HOT-WATER H EATING APPARATUS.

SPECIFICATION forming part of Letters Patent N O. 568,87 2, dated October 6, 1896.

Application iiletl July 13V, 1896. Serial No. 598,974. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH C. NORTON, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Hot- VVater Heating Apparatus, of which the following description, in connection with the accompanying drawings, is a specication, like letters on the drawingsrepresentinglike parts.

This invention has for its object the production of a novel and efficient apparatus for rapidly and thoroughly heat-ing Water, the construction ot' the apparatus being strong and durable and convenient to set up and operate, means being provided for regulating the heat and for running the apparatus with one or more substantially independent tirepots.

The various features of construction embodying my invention will be hereinafter described in the specification and particularly pointed out in the claims.

Figure l is a vertical sectional view of a hot-water heating apparatus embodying my invention. Fig. 2 is a transverse section thereof on the line o: Fig. 3 is a similar section on the line 0c', Fig. l, and Fig. 4 is a top or plan View of therre-pots with the reservoir omitted.

Referring to Figs. l, 3, and 4, I have shown the water-shell A as a casting comprising an outer Wall a a', the former of which is elliptical in cross-section, but upright, while t-he part a' slopes inwardly and upwardly to form a substantially elliptical cone. The inner wall h b corresponds in general contour to the outer wall, but I have herein shown two such Walls Within the outer wall to thus make a Water-space A', which divides the watershell into two fire pots or chambers F F', opening at ff' at their upper ends into the space within the external casing C of the heater.

Suitable grates g and g' are provided for the tire-pots, the Water-shell resting upon a base B, divided by a partition B into compartments, one for each of the fire-pots, and each provided with a suitable door BX,through which the ashes may be withdrawn and the draft regulated in usual manner.

As best shown in Fig. l, each of the iire pots or chambers is provided with a feedopening fXf'X, respectively, so that one or more of the'fire-pots may be used, as desired.

Owing to the inner separatingpart ct of the shell the various fire-pots are independent one of the other, and if only a small re is required one may be used, and more in proportion to the heat desired.

While I have shown herein the exterior of the shell as elliptical in form, it will be obvious that it maybe made otherwise, and by making the'dividing portion of the shell to correspond more than two tire-pots may be provided.

The products of combustion pass from the {ire-pot, through the openings ff', into the general combustion-chamber OX, and pass thence to the chimney by means of the main outlet O', communication being effected therewith by a two-way outlet C2 C3, respectively.

A damper c in the main outlet C' regulates the draft, and I have also provided dampers c2 and c3 in the part VC2 C3 for a purpose to be described, the outlet C2'being at or near the upper end of the combustion-chamber C and the outlet C3 near its base.

The Wall portion a' of the water-shell is I provided with an annular upturned flange a2, provided at suitable intervals with headed bolts or screws a3, (see Fig. 1,) upon which rests the lower edge of the water-reservoir R, the upturned flange preventing lateral displacement of the reservoir, while the bolts provide means for properly leveling in the erection of the furnace.

The water-reservoir consists of a cylinder main or body portion having a series of vertical lues r extended therethrough from its lower to its upper side and controlled by a suitable damper RX,having openings rx therein, (see Fig, 2,) which may be brought to` register with the tlues to permit free passage of the products of combustion through the main part of the reservoir, or the ilues may be more orfless closed by properly moving the damper. As shown in Fig. 2, the damper is suitably guided betweenribs or ridges/r' on top of the reservoir-body. The lower part of the reservoir depends from the main or body portion to form an annular outwardlydaring extension R', which is supported by the bolts a3 described, the said extension projecting over the upper part ot' the watershell, as clearly shown in Fig. 1.' The watershell A is provided with suitable water-inlets d5, and inlets T5 convey the water to the reservoir, entering the latter at the lower part of the extension R', while the inlets d5 enter the shell at or near its base.

The reservoir is cored out at r4 to admit the passage therethrough of pipes a6, which connect the upper end of the water-shell A with a water-head H, above the apparatus and exterior to its casing, from which head hot water is distributed, as desired, by means of pipes c', c2, and c3.

A pipe r1@ connects the top of the reservoir R with the head H, the damper being shown in Fig. 2 as slotted at 10 to permit the passage of said pipe without interfering with the operation of the damper. Now, if the dainper R is open, as shown in Figs. l and 2, the products of combustion will pass from the fire-pots or other iiues r, heating the water in the reservoir, and out at the top of the latter, and thence normally through the outlet O2 and main outlet O', the dampers c c being at such time open and the damper c3 closed.

If it is desired to cause the products of combustion to pass not only up through the body portion of the reservoir, but also down about the exterior of its extension R', the damper c2 is closed and the damper cs open, and it will be obvious by an inspection of Fig. 1 that the desired path ofthe products of combustion will be thus attained.

By shutting the damper R the products of combustion must pass up out of the fire-pots and then down between the extension R and the inclined water portion of the shell A', and then up and out through either the outlet O2 or C3, as desired, thus providing for various regulations of the heat.

The water-shell is continuous and the water can circulate entirely around the fire-pots and between them, and passing thence, as heated, to the head H, while the water entering the bottom of the reservoir is heated before it reaches its upper part on its way to its head.

A very convenient, simple, and effective' apparatus is thus attained, and one wherein the water is thoroughly and rapidly heated.

My invention is not restricted to the precise construction and arrangement herein shown, as the same may be modified or rearranged without departing from the spirit and scope of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In an apparatus of the class described, a plurality of independent iire-pots, a continuous water-shell surrounding and separating said pots, and aseparate feed-opening for each pot, extended through the watershell,whereby any or all of the fire-pots may be used as desired, substantially as described.

2. In an apparatus of the class described, a water-shell comprising an outer wall and a plurality of inner walls, to form a plurality of independent iirepots, the said inner walls extending between and forming the dividing water-space between the lire-pots, substantially as described.

'-l. In an apparatus of the class described, a water-shell comprising an outer wall and a plurality of inner walls, to form a plurality of independent fire-pots, and a separate grate and feed-opening for each pot, the said inner walls extending between and forming the di-A viding water-space between the fire-pots, and also extending below the grates to separate the ash-pits, substantially as described.

5. In a hot-water heating apparatus, a tirepot, a surrounding, externally-conical watershell, a water-reservoir having fines therethrough abovesaid fire-pot, a depending ilaring` base for said reservoir, a head, and connections between it, the reservoir and watershell, substantially as described.

7. In an apparatus of the class described, a water-shell, a plurality of fire-pots therein, an exterior casing, a water-reservoir within it and having an annular, depending extension surrounding the upper part of the shell, a two-way outlet for the products of combustion, and means to regulate the passage of said products, substantially as described.

S. In an apparatus of the class described, a water-shell, a plurality of fire-pots therein, an exterior casing, a water-reservoir within it and having an annular, depending extension surrounding the upper part of the shell, a series of fines in the centralportion of the reservoir, a regulator therefor, means to adjustably support the reservoir on the she11,a water-head, and connections between it, the water shell and reservoir, substantially as described.
